Patented Mar. 11, 1890.

N PETERS pmewmgnpw, wnningwm n c UNITED STATES To all whom it may concern:

Be it known that I, JAMES A.- ANGWIN, a citizen of the United States, residing at Oakland, Alameda county, State of California,

have invented an Improvement in Machines for Applying Hose-Couplings; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the classof machines for applying the couplings to hose g and my invention consists in the novel arrangement, construction, and combination of parts hereinafter fully described, and specifically pointed out in the claims.

The object of my invention is to provide a simple and easily-operated power-machine for applying the couplings to hose and securing them in their places. My machine, though applicable to any couplings, is specially intended for the coupling-heads and nipples of the hose of railway air-brakes.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a side view of my machine. Fig. 2 is an end view. Fig. 3 is a plan. Fig. et is an end view showing the attachment to the jaws of the clamp-blocks H. Fig. 5 is a side view showing the attachment of knife I. Figs. 6 and 7 are views of bars to be attached to bar F. Fig. 8 is an edge view of knife I. Fig. 9 is a view of bar F.

A is a frame or stand. Upon one end of this frame is fixed the stationary block or jaw B, opposing which is the sliding block or jaw C, said jaws having their opposing faces grooved to receive and hold the hose which is inserted between them, and the grooves of the jaws are at their inner ends cut out a little deeper, as shown at b and c, so as to permit the expansion of the hose which is held between them.

Upon the top of the frame or stand A is a cylinder D, having a slotted piston-rod d, to which is connected the coupling-block E. This block is a forked one, and is provided with an elongated vertical slot e, passing through it at right angles to its fork-opening. The block and the piston-rod are guided by 'means of a removable key CZ', which passes down through the slotted rod.

F is a bar which forms a lcombined expander and coupling-headholder. It is made PATENT OFFICE.

SPECIFICATION forming part of Letters Patent No. 423,106, dated March 11, 1890.

Application led October 4, 1889. Serial No. 326,026. (No model.)

.elbow-shaped, having at the end of one of ,its arms the conical expander portion f and `atthe end of its -other arm a shape or construction-such as is shown al ff adapting it for the ready engagement of the couplingn head of aWestinghouse air-brake hose. This bar is iitted to the forked coupling-block E,

and is secured thereto by means of a pin f2, 6c v which passes down through its angle Vand through the elongated slot e of the couplingblock. t

The machine as farV asdescribed has the following operation: The hose is placed betweenthe jaws B and C with its endprojecting very slightly beyond them. The sliding jaw C is then moved up to the hose, so as to bind it between itself and the fixed jaw B with sufficient power to resistithe forcing in 7o of the coupling. The angular bar F is pivi oted in the forked block E insuch a manner that its expander-point f -extends directlyy forwardly and in line with the end of the hose. In order to guide it truly and insert it, 7 5' in the hose primarily, said bar is slid backf- Y wardly, its pin f2 moving in the elongated slot e, so as to clear the hose, and is then slid.- forwardly again in order that its Yconical point f may enter thehose Then the iston- ,SQ rod cl is forced forwardly, thereby forclngthe conical point f of the expander into'the end' l of and expanding said hose, which yields in the enlarged portions band c of the jaws.

As soon as the hose is expanded the pistony rod d is withdrawn and the exp'ander-pointje v. removed from the hose by -thereturn ofthe l piston-rod under the power of a release-,spring cl3 in thecylinder. As soon as it isfree'the angular bar is turned on its pivotal center f2 9o to a position at right angles, so that its end f is brought into line with the hose. When the expanderpoint is withdrawn, the expanded end of the hose remains practically within the enlarged portions b and c of the jaws. The ordinary coupling-head is now easily inserted in the vexpanc hose, and then the bar F is slid forwardly until the end f of the coupling-bar engages the coupling-head, and pressure then from the hose with the necessary tightness. p v To insert the nipplecoupling, it is obvious t that the end f of the angular barmightbe ed end of the 7" roo f the cylinder forces the coupling-head into. U

suitably formed for this purpose; but I prefer to `have a separate bar of suitable construction-such as is shown` by (ub-which I couple on by a ping to the end of the angular bar F, said bar being adapted to iit and force the nipple in. n AIt will be readily understood that these forcing-bars may be made of any suitable construction adapting them to engage the particular kind ofv couplings which are to be put into the hose. After the coupling has been forced -into the hose said hose is'removed'from the holding-jaws B and C, and then the usual. clamps are placed about the hose ends to hold the couplings in place. These clamps consist of curved pieces of metal encirclingl the hose and having seated between their Vmeeting ends a securingbolt. The clamps are usually applied by being placed between the straight-faced jaws of a vise; but in employing such meansit is obvious that the clamps are not forced about the hose to vconform to its curvature, but are rather flattened out. To better Vclamp them, and also to provide means in connection with my machine which can be readily used, I have the .curved-faced opposing jaws H, the stem h of each of` which is flanged and is adapted to fit in a grooved-out socket c and '11', formed in the tops of the blocks or jaws C and B. These clamp-jaws 'are'readily inf serted in place, and the hose end, with its clamp, is placed between them. Then by mov ,ing the block C up the two jaws H bind upon and press the clamp firmly about the hose, so that its bolts may be set up. A standard h rises from one of the jaws H, and through this is to pass freely the shank of the wrench to screw up the nuts on the clampbolts.

In order to cut the hose into any suitable lengths, I have a' cutting-blade I, which is adapted to be connected in a vertical plane with the coupling-block E. This is done by removing the key d', turning the piston-rod and coupling-block E through aquarter-revolution, so that its fork-opening lies vertically, and reinserting said key d in a horizontal v plane through the horizontal slot c Then the knife.V I is inserted vertically in the fork-opening of the coupling-block and secured therein by a pin. A grooved temporary block J is then laid upon the table parallel with and against the jaws B and C, and in the groove of this block the hose is laid, so that when the knife is moved forward it will lcut it at right angles. f

The cylinder D is intended for use in connection with compressed air, which is supplied to it by a pipe K, controlled by a cock 7c, a suitable relief-valve lo being provided.

The sliding jaw O is operated by the following mechanism: Secured under the table or stand is a second air-cylinder L, the pistonrod Z of which is connected with the lower end of a lever IWI, which is pivoted at m and has its -upper end bearing between studs or pins m on the sliding jaw C'. Airis supplied to the cylinder through a pipe N, controlled by cock n, forces the piston forward and operates the lever M to set the jaw C up. A spring-controlled rod O, connected with the lever M,

moves the parts back again, a suitable escapevalve at n beingprovided.

I am aware that in machines for applying hose-couplings the hose is held in a suitable clamp, while the coupling is forced into it by means of power devices, and I do' not, therefore, claim such, broadly; but

What I do claim as new, and desire to s eure by Lett-ers Patent, is-
